Behavioral states and state-related heart rate and motor activity patterns in the newborn infant and the fetus ante partum. A comparative study. III. Analysis of sleep state-related motor activity patterns.

Evaluation of fetal movements revealed a striking difference of motor activity during assumed quiet sleep and active sleep in the fetus. Furthermore, motor activity was found to be enhanced in post-term fetuses. Consequences for the methods of fetal acceleration determination (FAD) and daily fetal movement count (DFMC) are discussed.

[The early cytological diagnosis of carcinoma of the uterine body with the Gravlee jet-washer (author's transl)]. / Zur zytologischen Frühdiagnostik des Uteruskarzinoms mit der Spülcurettage nach Gravlee.

A group of 108 patients who had a curettage for post-menopausal bleeding had a cytologic investigation with the Gravlee jet-washer prior to the curettage. 79 jet-washes (73.1%) were cytologically negative, nine (8.3%) were positive, two (1.8%) were false negative. False positive cytology did not occur. In 18 cases (16.6%) the material was insufficient for cytology. The accuracy of the jet-washings was 82%.

[Acute reduction of uterine blood flow and fetal heart rate changes in pregnant sheep near term].

Five merino sheep near term were used for acute preparations to investigate the influence of basal uterine blood flow (UBF), basal fetal oxygenation and basal fetal heart rate (FHR) on FHR changes elicited by acute reduction of UBF. The ewes were anaesthesized with pentobarbital and Alloferin was given for relaxation. Ventilation was maintained via a tracheal tube by a Starling pump. Maternal heart rate, arterial pressure and intrauterine pressure as well as fetal heart rate and umbilical artery pressure were recorded continously. Initially blood flow was recorded by cuff flow meter sequentially in both uterine arteries for a short time in order to determine total UBF and the ratio of flows. During the UBF reduction sequence flow was recorded in the artery of the gravid horn continously and measurement was corrected according to the initial ratio of flows in both arteries, presuming that this ratio would remain constant throughout the course of the experiment. Repetitive and progressive acute reduction of UBF (approximately 25%, 50% and 100% from basal UBF value) was achieved three times, lasting 120 sec each and each approximatly 12 min apart, by flow meter controlled partial or total occlusion of the aorta abdominalis of the ewe with a balloon catheter inserted into the aorta. (In some cases the lateral abdominal section was left open and the aorta was compressed manually). Before, 90 sec after the beginning and 10 min after the end of UBF reduction blood samples were taken from the fetal catheters (Fig. 3). In two preparations this sequence was repeated once after complete recovery of FHR.
